Title: Improvements relating to separating machines
IPC: B02C13/22
Filed: 1926-03-23
Abstract: 263,660. Plath, G. March 23, 1926. Pneumatic separating. - In separating- machines of the type in whicli the material is projected from a rotary distributing disc into an upwardly directed current of air which carries off the lighter particles and deposits them in suitable receptacles, the distributing device is constructed to act also as a comminuting or grinding machine and is disposed in the inner of two concentric chambers through which the current of air circulates. In the construction shown in Fig. 1, the grinding and distributing device comprises a rotary disc 3 and a stationary disc 5 with pins 4, 6. The stationary disc 5 is secured to a rigid tubular member 7, either cast or formed of wrought iron plates, which also serves as a charging member and which is secured to strong beams 9. Bearings for the shaft 2 of the rotary disc are provided near the lower end of the member 7 and in a plate 11 secured to the beams 9 and having openings 10. An outer and inner casing a, b form two chambers d, c through which a circulating current of air is moved by a fan e carried by the disc 3. The air passes upwardly and through the comminuted material in the inner chamber, carrying off the light particles which are deposited in the outer chamber. In the modification shown in Fig. 5, the lower disc 5<1> is stationary, being carried by rigid supporting arms 15, and providing a foot-step bearing for the shaft 2 to which is secured the disc 3<1>. The fan b<1> is carried at the upper end of a funnel member 13, and a separate charging funnel 7' is provided.

Abstract: 457,368. Automatic guns. FABRIQUE NATIONALE D'ARMES DE GUERRE SOC. ANON., Herstal-lez-Liege, Belgium. Aug. 21, 1935, No. 7972/36. Convention date, Sept. 28,1934. Divided out of 457,354. [Class 92 (ii)] Relates to auto matic guns in which the rear of the breed casing is closed by a vertically sliding plate 13 carrying pivotec aiming grips 31, 32 According to the in vention, in order t( prevent withdrawal of the plate 13, the grips are provided with projections 31a 32a which engage notches 35, 33 in the casing when the grip: are turned. The arrangement is sucl that, in the trans verse aiming position shown, the grip 32 effects locking of the plate but, when the grips are turned into the longitudinal position, the grip 31 effects the locking. To permit removal of the plate the grip 32 only is moved into the longitudinal position. The usual firing button is locked by projections 31b, 32b on the grips when these occupy the longitudinal position.

Title: Improvements in or relating to methods of absorbing carbon dioxide
IPC: C01B32/50
Filed: 1959-03-09
Abstract: In a cyclic process for recovering CO2 from gases by successive absorption in, and desorption from, an aqueous solution having a pH greater than 7, e.g. alkali metal carbonate, containing arsenite as described in Specification 798,856, wherein absorption is decreased by the presence of arsenate, part of the solution is withdrawn from the process and the arsenate is heated in the presence of a reducing agent to above 150 DEG C., e.g. 250-280 DEG C., to convert arsenate to arsenite, which is returned to the process.  Reducing agents are formaldehyde, acetaldehyde, methyl, or ethyl, alcohol, formic, oxalic, or tartaric, acid or salts thereof, hydrazine or salts thereof, potassium hydrosulphite, arsenic, antimony, bismuth, a sulphide, hydrocyanic acid, or potassium cyanide, or ferrocyanide. The heating may be effected in an autoclave lined with noble metal, e.g. silver, with stirring, and CO2 should be present, either added as such, or due to the presence of bicarbonate in the solution. Before heating, the solution may be concentrated, or the arsenate may be extracted, e.g. by crystallising, or precipitating as magnesium ammonium arsenate, and heated separately.  Also the reducing agent may be added to the solution, which is evaporated to dryness, and the residue heated and redissolved.
